Aspen Leaf is a private irrigation dam located in Gunnison, Colorado, specifically in the city of Paonia. Completed in 1947, this Earth-type dam stands at a height of 26 feet and has a hydraulic height of 22 feet, with a structural height of 30 feet. It serves the primary purpose of irrigation, with a storage capacity of 65 acre-feet and a surface area of 5 acres.

Managed by the Colorado Department of Water Resources (DWR), Aspen Leaf is regulated, inspected, and enforced by the state agency to ensure its structural integrity and safety. Despite being classified as having a low hazard potential, the dam poses a high risk due to its condition assessment being rated as satisfactory. The last inspection was conducted in June 2015, with a frequency of every 6 years, and emergency action plans are yet to be prepared.

Situated along Muddy Creek-TR, Aspen Leaf plays a crucial role in the local water resource management, providing irrigation water to the surrounding agricultural lands. It stands as a testament to Colorado's commitment to sustainable water infrastructure, balancing the need for water supply with environmental conservation and safety considerations.
